Superior alternating hemiplegia (Weber's syndrome)- Case report

Weber's syndrome revealing a Percheron artery infarction: A case report

“…Its incidence is unknown and it rarely occurs in isolation. 10 , 11 Mesencephalic and Percheron artery infarction with Weber's syndrome is a rare and difficult clinical finding. 12 In our patient, the common oculomotor nerve damage was not accompanied by pupillary damage.…”

Weber’s syndrome revealing a Percheron artery infarction: a case report

“…Indeed, Weber's syndrome is part of the midbrain syndrome and is characterised by a contralateral hemiplegia associated with an attack on the homolateral common oculomotor nerve. Its incidence is unknown and it rarely occurs in isolation (10,11). Mesencephalic and Percheron's artery infarction with Weber's syndrome is a rare and difficult clinical finding (12).…”

Diagnosing Weber syndrome requires compliance with diagnostic criteria and compatibility with cerebral imaging

“…We eagerly read the article by Sheikh Hassan et al reporting on a 62 years-old male who developed disorientation, cognitive decline, incomplete right oculomotor palsy, and left hemiparesis one week prior to admission attributed to acute ischemic right midbrain stroke [ 1 ]. The stroke was classified as Weber syndrome and attributed to arterial hypertension as the only cardiovascular risk factor [ 1 ]. The elegant study has limitations that require reassessment.…”

“…There is disagreement with the diagnosis Weber syndrome [ 1 ]. Arguments against Weber syndrome are that the patient presented with disorientation and cognitive dysfunction, that the oculomotor nerve palsy was incomplete, and that the lesion shown in Figs.…”

“…On the contrary the lesion corresponding to the diffusion-weighted imaging (DWI) hyperintensity in Fig. 1 is clearly hyperintense on apparent diffusion coefficeint (ADC) maps [ 1 ]. Therefore, the description of the stroke as acute is not justified.…”
